Be it known that I, CORNELIUS YOUNG, a citizen of the United States, and aresident of Selma, in thecountyof Dallas and State of Alabama, haveinvented certain new and useful Improvements in Cotton-Seed Hullers,-

' part of this specification.

This invention. has relation mainly to improvements in mills for cleaning and reducing cotton-seedand separating the hulls from the meal; and it consists in the novel concompartment B around the central shaft 6 or in such a manner as to cause the feed to flow toward the lateral opening 17 into the second compartment B. This compartment is of larger diameter and somewhat deeper than compartment B, and its upper portion is higher, forming a dome or raised portion b. In the bottom of this compartment, below the boaters thereof and below the STATES screen a' is a basinor pocket F rovided witha slide-bottom c, which when withdrawn precipitatest-he contents of such pocket into a receiver-F". uponan extension of shaft e in this compart- A feeding-reel E is provided ment,which agitates the material flowing into it from the compartment B andforces' the seedtoward the reducing-cylinder, which is exposed in this compartment at the opening e.

A block F, of substantially triangular pris matic form, is provided between the com partment B and the reducing-cylinder and forms the top or cover of the space therebetween; This block has a concave-cylindrical surface in close relation to the reducing-cylinder and acting to closely confine the seed to the knives thereof in approaching or feeding to the concaves K for the purpose of a positive reducing effect. This block is adjustable forthe purpose of taking up wear, &c., and acts also as a guard or fender to prevent injurious extraneous matter from being carried to the concaves. is thrown by the boaters therein against the wall f and is deflected therefrom upon the cylinder G. This wall f of the feed-block forms the top of the passage through which the seed is thrown from the beater-compartment to,

the reducing-cylinder, said passage having a substantially tangential relation with respect to both said compartment and cylinder. The block may, be adjusted to work closer to the reducing-cylinder by placing packing f between its upper surfaceand that of the framework, to'which the feed-block is secured by means of suitable screws or bolts f. Extra neous mattersu ch as gravel, stems, and par-Y ticles of ironis designed to fall during. the agitation of the contents of this compartment; into its bottom portion or basin F, from which} such matter may be discharged into a receiver F" at such time as it may be. desired by withdrawing the slide 0, this separation of such heavy extraneous matter being rendered more complete by the dome 1), into which it will be thrown by the heaters, thuschecking its velocity and facilitating its fall into pocket F.

The grinding or reducing compartment is cylindrical and is provided with a grinding or cutting roller G, working therein, and the The seed in the compartment 13 concaves K K, which are secured to the framework. The roller G on the shaft g is formed with longitudinal recesses h, the walls of which are double inclined or beveled in each direction and the bottom of which is flat and provided with perforations h for the reception of bolts h, the heads of which are countersunk. Secured by these bolts in said recesses are the V-form bars g, by which the knives H and H are secured in oppositelyinclined position. Each knife consists of a plate of high-grade steel which should be capable of being bent cold. The body of each knife being held clamped between the sloping bearing of the recess h and the beveled side of the bar g at an angle of about fortyfive degrees, the bent cutting edges are designed to have a low inclination beyond the roller-surface, rising therefrom to a height less than the thickness of a cotton-seed or so that a disintegration of the seed will be ef fected. The forward knife of each set having its cutting-flange bent at a lower angle with the plane of the body of the knife than is the case with the rear knife of the same set has a more positive action. When the cutting-flanges are worn out, the knives may be removed and straightened and then sharpened and rebent.

The concaves K K are secured to the framing by means of suitable bolts 7a, which also hold parts of the concaves together. Each bolt is provided with a shoulder at Z and is threaded above and below said shoulder. On the shoulder rests the perforated concave plate 70', and through the perforation of this plate project the ends of the grinding-teeth L, which consist of round steel nails having flat flange-heads. The outer plate 7c of the concave is correspondingly perforated to receive these grinding-nails, the flange-heads of which rest against its outer surface. A steel projecting plate Z is placed on the heads of the teeth, and upon this rests the cast-iron cap-plate L. Usually a cushion-piece of yielding material (leather or thin wood Z) is placed between the cap-plate L and the steel plate Z in order to provide against-- too great rigidity of the points of the grindin -teeth in their work.

The plates 70, It", and L are held together and to the framework by the bolts It It, which pass through perforations in the ends of said plates. A nut or, engaging that end of the bolt is below its shoulder, secures it to the frame. A nut 91. above the concave plate 70 holds it to position. A nut n below the perforated plate 7t holds the latter plate in place and a nut 01 holds the cap-plate down. To prevent vibration of the middle portion of the perforated plate a short bolt m holds it to the middle portion of the cap-plate. The teeth can be adjusted to project more by loosening the nutsunder the perforated plate 76" and tightening those on the cap-plate. Reverse manipulation of these nuts will shorten the projecting ends of the teeth.

The material disintegrated by passing between the concaves and the kniferoller, which revolves at a high rate of speed, is thrown through the passage or spout P into the separator D, whereof the lowerportion D' is separated from the upper portion D by means of a concave or semicylindrical screen S, designed to allow the meal to pass through its meshes into the lower part. The reel R is designed to be provided with spiral blades or such as will cause a gradual movement of the material toward the outer end of the separator, where the hulls are discharged, an opening at 25 being provided for this purpose.

In the operation of the invention the seed is fed to compartment B, and while being fed endwise thereof the heaters therein act to drive chaff and other light stuff, sand, and small gravel through the screen, nails, large gravel, &c., traveling with the seed into compartment B, when they drop into pocket F, thus thoroughly cleaning the seed and saving the knives of the reducing-cylinder and the concaves from injury.

Having described this invention, what I claim, and desire to secure by Letters Patent,
